lM PRQVEMENT IN PAPER- RIULINIG MACHINES.

Specification forming part'of Letters ratent No. 200,553, dated February19,1878 applicationfiled I August20, 1877.. t I" To all whom it may,concern;

Be it known that I, J ornv, MoAnAMs, of Brooklyn, in the county of Kingsand State of New York, have invented certain Improvements on Means forTurning Paper in Ruling- Machines," of which the following is adescription, reference being had to the accompanying drawing, formingpart of this specification.

This invention relates to means for shifting or turning paper inruling-machines to effect a cross-ruling of the paper as the latterpasses through .the rulin g-machine and the invention consists'incertain novel combinations of devices, whereby the paper, after ithasbeen ruled by one set of pens with parallel lines running in onedirection, is passedby a conveyer to the turning devices, which operateto give to the paper upon the surface on which it rests a quarter-turn,so that said paper, on having its feed continued in the same directionas before, may be ruled by a second set of pens in rear of the formerpens, with lines crossing at right angles to the lines with which it waspreviously ruled.

Figure 1 represents a plan of the paper conveying and turnin g devicesof a rulin g-machine having my invention applied. Fig. 2 is alongitudinal vertical section of the same on the line as w, and Fig. 3 atransverse section thereof on the line 3 Fig. 4. is a detail section onthe line 1) v.

A represents the primary endless-string conveyer or carrying device, theupper surface of which moves as indicated by the arrow 2, and whichserves to convey the paper, after it has been ruled in one direction byone set of pens, to the turning devices, which give the paper aquarter-turn between said carrying device A and an endless apron, B,which moves in the same direction as the conveyer A, and delivers thepaper to a string or other carrying device that takes it to the next setof pens, which rule the paper in a direction transverseto the formerruling. In this way or by these means the motion of the paper is notchanged for ruling it with lines at right angles to each other, and thetwo sets of pens for ruling at right angles may be arranged one in frontof the other; but the paper itself is simply or bodily turned betweenruling it in one direction and ruling it at right angles thereto.

Themeansfor thus turning the paper G between the carrying device A andthe endless apron B are substantially as follows: D is an under-driven.roller 0r wheel, arranged to revolve, as regardsthe upper portionof itsperiphery, in the same direction as the feed by the string conveyer A,at one sideand in rear of which latter it is situated, and. caused toslightly projectthrough a ;table-s11rface,-E,.be-

tween the string conveyer A and apron B,- Abovethis wheel D is alooseupper roller 0r wheel, G, between which and the under wheel or roller Dthe paper 0 is introduced by the conveyer A,.in order that said papermay be turned, through the hold upon its one side by the wheels D and G,from the position shown for it by full lines in Fig. 1 to that shown forit by dotted lines in the same figure, said wheels D and G operating inconnection with suitable retarding or checking devices, as hereinafterdescribed.

The loose wheel G is fitted to turn upon an elastic shaft, H, arrangedover the shaft which carries the driven lower wheel D, and rigidlysecured at its end b, which is farthest from the wheel G. This elasticconstruction of the shaft 7 H provides for a yielding and self-adjustinggripe or hold of the wheels D and G on the paper.

As these wheels D and G receive from the v string conveyer A the forwardedge of the paper 0 at its one side in between them, said paper isrestrained from getting out of line, and from being projected throughsaid wheels before being turned, by its front edge coming into contactwith or entering beneath one or more retarders or checking devices, I,on the inner side of the wheel G at a greater or less distance from thelatter. Said retarders are constructed with a bent or curved arm, whichoverlaps the front edge of the sheet as it is entered beneath them, andare furthermore constructed to clip or receive within their upper endsor portions the elastic shaft H, which thus gives to them an easy oryielding action.

By the rotation of the lower wheel D and elastic gripe of the upperwheel G on the forward edge of the sheet at its one side, subject to thearresting action of the retarders or checking devices I, the sheet orpaper is bodily turned by the wheels D and G for one-quarter of a turn,or thereabout, on or over the table surface E, conveyerA, and apron B,onto which latter it is fed by the wheels D G. Such turning action onthe paper by the wheels D G carries the forward edge of the sheet fromunder the retarders I as said Wheels commence to turn the sheet, andafter the sheet has been turned and fed by the wheels D G onto the apronB the impetus given to it in turning is or may be arrested by a rolleror other stop, K, to keep the inner edge of the sheet in line with thefeed of the paper by said apron. This stop K is carried by an arm, g,adjustable through a socket, h, which, in its turn, is adjustable along,and capable of being secured by set-screw on, the elastic shaft H, thatnot only serves to bear the wheel G on the paper between said wheel andthe wheel D, but also has a torsional elasticity by constructing itwltha flattened portion, 8, whereby the stop K is kept down on the apronB.

By employing a close apron, B, instead of a string conveyer to catch andconvey the sheet after it has been turned, the edges of the paper orsheet are prevented from catching while being turned, and abearing-surface is provided for the stop-roller K.

I claim-- 1. The combination, with the endless conveyers A and B, of thelaterally and intermediately disposed wheels or rollers D G, and

one or more paper retarding or checking devices arranged to one side ofsaid wheels or rollers, and constructed to stop or hold the sheet at itsforward edge while being turned by the wheelsor rollers D G,substantially as specified.

2. The elastic shaft H and its loose wheel or roller G, in combinationwith thewheel or roller D, having a positive motion, the conveyer A,near one side and in rear of which said wheels or rollers are arranged,and one or more paor more paper retarding or checking devices,-

I, arranged to one side of said wheels or rollers, and constructed tostop or hold the sheet at its forward edge while being turned,substantially as specified.

4. The stop K, in combinationwiththe wheels or rollers D G, essentiallyas described.
